I saw the same report - no notice white out conditions. People panic and do stupid things when this happens.From the reports I saw on tv went from normal conditions to a white out very quickly. I try and not speculate about why something happens, regardless of the reasons it sucks when we have such a big accident.
The report of near instantaneous White Out conditions hit national news. The exact same, doubtful unless we watched the same national news, but the report of the white out - yes.
